Mechanism of CO2 Corrosion of Mild Steel: a New Narrative

Corrosion, 2018
The polarization behavior of API 5L X65 mild steel at various pH values and CO2 partial pressures was investigated at a high flow velocity. In contrast to the commonly accepted mechanistic view of CO2 corrosion, it is shown that the direct reduction of

Electrochemical Model of CO2 Corrosion in the Presence of Quaternary Ammonium Corrosion Inhibitor Model Compounds

Corrosion, 2019
The oil and gas industry utilizes surfactant-type organic corrosion inhibitors to mitigate internal pipeline corrosion. Changes in corrosion rates due to inhibitor addition have been related to adsorption isotherms as a function of the inhibitor ...

An Experimental Investigation on the Effect of Salt Concentration on Uniform CO2 Corrosion

Corrosion, 2019
Hydrocarbon extraction from underground reservoirs is typically accompanied by the production of water as a by-product. Dissolved salts are a general characteristic of produced water.

Galvanic Influence of CO2 Corrosion

CORROSION 1989, 1989
Abstract Galvanic acceleration of internal corrosion of carbon steels in gas and oil well environments can occur because dissimilar materials are coupled together, when protecting corrosion films are locally destroyed by turbulent flow or particle erosion, or when concentration gradients occur in the environment due to deposits ...

Mississippi CO2 Project - Corrosion Control

CORROSION 1986, 1986
Abstract Shell Western E&P Inc.'s Mississippi CO2 Project is composed of the CO2 source wells at Northeast Jackson Dome and three flood fields: Little Creek, West Mallalieu, and Olive. Project design has been dominated by the need for a comprehensive corrosion control plan.

Why Does Glycol Inhibit CO2 Corrosion?

CORROSION 1998, 1998
Abstract CO2 corrosion of carbon steel and its inhibition in mixtures of water and ethylene glycol (MEG) or diethylene glycol (DEG) has been studied at 1 bar CO2, 25 °C, pH 5 under natural convection conditions. Corrosion rates predicted by the glycol at 1 bar CO2,25 °C, pH 5 under natural convection agreement with the experimental ...

PREDICTION OF CO2 CORROSION GROWTH IN SUBMARINE PIPELINES

Malaysian Journal of Civil Engineering, 2018
The paper presents a probabilistic-based methodology for the assessment of a pipeline containing internal corrosion defects. Two different models have been used to predict the future CO2 corrosion rates namely a linear growth and the deWaard-Milliams ...

Environmentally Friendly Inhibitors for CO2 Corrosion

CORROSION 2002, 2002
Abstract There is an increasing need in the petroleum industry to develop green products due to more severe environmental legislation. Recently, several environmentally friendly corrosion inhibitors became available commercially. We evaluated the performance of five of these commercial green corrosion inhibitors in CO2 saturated 3 ...

Fundamental Aspects of CO2 Corrosion

CORROSION 1983, 1983
Abstract The paper summarizes the present day knowledge on the electrochemical corrosion of metals in oxygen-free CO2 environment. Fundamental aspects of the corrosion mechanism, kinetic factors and effects of influencing parameters on uniform and localized corrosion are discussed emphasizing problems in the oil and gas industry.

Modelling of CO2 Corrosion Mechanisms

1994
A model of electrochemical reactions occurring in a water — CO2 system is presented that takes into account the following electrochemical reactions: hydrogen ion reduction, carbonic acid reduction, direct water reduction and anodic dissolution of iron. Performance of the model is demonstrated through a study of the effects of some key parameters in CO2
